Radial capacity and hemodynamics evaluation in vitro and implantable feasibility validation in vivo of thinner bioresorbable polymer vascular stents

BMEMat, EarlyView.
A series of in vitro experiments, numerical simulations and in vivo experiments were conducted to jointly evaluate the effects of different thicknesses of bioabsorbable polymer vascular stents on their radial capacity, hemodynamics and in vivo outcomes.

Speaker-following Video Subtitles

, 2014
We propose a new method for improving the presentation of subtitles in video (e.g. TV and movies). With conventional subtitles, the viewer has to constantly look away from the main viewing area to read the subtitles at the bottom of the screen, which ...

Expanding Space: the Root of all Evil? [PDF]

, 2007
While it remains the staple of virtually all cosmological teaching, the concept of expanding space in explaining the increasing separation of galaxies has recently come under fire as a dangerous idea whose application leads to the development of ...

The spread of non‐native species

Biological Reviews, EarlyView.
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

Asymmetrical Expansion of Balloon-Expandable Transcatheter Aortic Valve Prostheses: Implications for Valve Hemodynamic and Clinical Outcomes.

JACC: Cardiovascular Interventions
BACKGROUND Asymmetrical expansion of transcatheter heart valves (THVs), manifesting as stent frame deformation, is an occasional fluoroscopic finding in transcatheter aortic valve replacement (TAVR).

Predicting Coronary Occlusion Risk during Redo‐TAVR at First TAVR: Asymmetric Calcification Causes Failure

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background and Aims Predicting coronary artery occlusion due to sinus sequestration (SS) during a second transcatheter aortic valve (TAV) procedure using pre‐procedural computed tomography (CT) after the first TAV replacement (TAVR) is underreported.

From 3D Point Clouds to Pose-Normalised Depth Maps [PDF]

, 2010
We consider the problem of generating either pairwise-aligned or pose-normalised depth maps from noisy 3D point clouds in a relatively unrestricted poses. Our system is deployed in a 3D face alignment application and consists of the following four stages:

Balloon‐Expandable Versus Self‐Expanding Valves in Low‐Flow, Low‐Gradient Aortic Stenosis: Does Valve Type Matter?

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The optimal choice between balloon‐expandable (BE) and self‐expanding (SE) transcatheter heart valves (THVs) in patients with low‐flow low‐gradient aortic stenosis (LFLG AS) undergoing transcatheter aortic valve replacement (TAVR) remains unclear.
